To all whom t may concern.'

Be it known that l, MARTIN FEYBUSCH, a subject of the- Emperor ofGermany, and a resident of New York city, in the county and State of NewYork, have invented ycertain new and useful llmprovements in Label-Feeding Devices, of which the following is a specification.

This vinvention relates to a device by means of which labels or similararticles may be withdrawn from a magazine and conveyed to a gumlning orother machine for subsequent treatment in a simple, and re, liablemanner.

lln the accompanying drawing: Figure 1 is a plan of a label feedingdevice embodying my invention; Fig. 2 an end elevation thereof; Fig. 3 asection on line3-3 Fig. 1; Fig. 4 a detail of the glue pot; Fig. 5 adetail of the clutch mechanism, and Fig. 6 a detail of the plunger.

. in this way `the size of the magazine may be adjusted. The magazine isopen at its bottom, and is centered over slot. 4, the labels l2 beingsupported by a plurality of lugs 13 Aprojecting inwardly from plates 5and 6and located in a plane above'the surface ofthe platform.

Beneath platform 3, there is yournaled in frame l, a pair of rollers 14,15 over which passes an endless conveyer belt 16, composed of rubber orother flenible material, the upper run of said belt beingaccommodatedwithin slot 4.

Means are lprovided for applying an adhesive to the belt, means fordedecting the upper gumnied run of the belt into engagement with thelowermost label, and means for advancing the belt together with thelabel adhering thereto, to the gumming or other machine for furthertreatment. As

' shown, a glue pot 17 is mountedy on frame 1 beneath the lower run of.belt 16, and into Specification of Letters Patent.

this pot dips a transfer roller 18 which con- I s tacts with such lowerrun and isthus adapted to applyithe adhesive thereto. Roller 18 isrotated as follows: The power shaft 19 driven by belt 20, drives'bypulley 21, belt 22, and pulley 23 a stub shaft 24, which is intergearedat 25 with the shaft 26 of roller 18. Shaft 26 is engaged by a scraper27, depending from a slotted cover 28, such cover constituting a scraperfor roller 18. Cover 28 together with scraper 27 may be adjusted' by aset screw 29, and may be clamped in po- `llt is preferred to pivotallymount `glue I pot 17 upon a shaft 31, so that by tilting the pot, the deth to which vthe transfer roller 18 enters t e liquid adhesive isregulable. The means for tilting the pot comprise a xed screw'stem 32,that is engaged by a threaded head 33, carrying a pair of disks 34 whichstraddle a pin 35' carried by thel glue pot.` Head 33 maybe providedwith Spanner holes and by turning it, the pot may be tilted eitherupward or downward Von shaft 31. en the belt is advanced in an'intermittent manner, `as hereinafter described, its ed lower run will intime l form its upper run, which is thus coated with the adhesive on itsupper face and directly4 beneath the label magazine. This upper run isengaged by a 'plunger 36, that is located directly beneath the same,-and extends sidewise from a plunger rod 37, the shaft 38\of which isguided in a bearing 39, and is inHuenced by a spring 40. Flinn,l

ger 36 is actuated from shaft 19"as follows: Shaft 19 is by wheels 41,42 intergeared with a shaft 43 carrying a cam 44 which is engaged by afeller 45 on an arm 46. This arm is connected to a rock shaft 47 hbvingan arm 48 that enters a notch of `rod 37, so that by the rotation of cam44, the plunger will be alternately raised and lowered. As the plungerisraised, it will be projected upwardly through slot 4 of table 3, andwill accordinglyV expand the upper run of belt 16. This run is thuslifted by the'plunger through slot 4, so as to rise into the plane ofthe supports 13 within the label magazine and come into contact with thelowermost label 12 to which itA becomes attached. llnasmuch as themagazine and the labels contained therein, extend a distance sidewiseAbeyond the slot, the belt will not underlie the entire bottom of label"1,2, but will contact with the same only along its central line, thelright and left portions of the label remaining free, so that an undulyfirm adl motion consists in an intermittent advance by'means of whichthe label is carried to .its place of destination. The means forimparting an intermittent forward movement to the belt are as follows:Upon' shaft 43 is mounted a second cam 49 engaged byva roller 50journaled to` one end of a slotted rod 51, which is engaged by a guidepin 52.

` yThe other end of-rod 51 ispivoted at 53 *toward kand 'between a tothe oscillative shank of a toothed seg'- ment 54, turning on center 55.Segment 54 engages a pinion 56 fast on the hub of a clutch box 57 thatis loosely mounted on the shaft 58 of roller 14. To'clutch box 57 arepivoted pawls 59 adapted to engage a ratchet wheel 60 fast on shaft 58.The correlation of the parts is such that whenl segment 54 is swungforward or to the right,

it will by the mechanism described, rotate roller 14, so as tocorrespondingly advance belt 16, Vwhile during the return movement ofthe segment, no motion is transmitted to the roller. In this way thedesired intermittent forward movement will be imparted to belt 16,whereby the labell 12 riding thereon, will be carried from beneath themagazine toward the delivery end of the device.

ere there are provided a pair of stripper plates 61 that flank' slot 4,and project into close proximityto belt 16, so as to peel the label olfthe same. distance beyond roller 15, and conduct the forward end of thepartly stripped label pair of conveyer shafts by means of which thelabel is carried to the gummingmachine to be operated upon. As shown,power shaft 19 assumes the function of one of the conveyer shafts, whilethe other shaft 62- is mounted in close proximity thereto and isprovided with milled gripping sections 63.

The operation of the device will be apparent from the foregoingdescription. The belt after being coated with adhesive is, at rest,raised by the plunger into contact with the label. Upon the recession ofthe' plunger, the belt with the label adhering thereto, resumes itsnormal position,

ment, to carry the label toward vthe strippers. Here the label is peeledoff the belt and is by the conveyer shafts, carried to 'Strippers 61extend a the gumming machine. YIt will be seen that by theconstructiondescribed, all grippers and their actuating devices areentirely clispensed with, the lbeltassuming the dual function ofwithdrawing the label from the magazine and of feeding it away from themagazine .after its withdrawal. In this way the construction of thedevice is greatly simplified while a positive and reliable action isinsured.
